This invention is directed to prodrugs that can be activated at the preferred site of action in order to selectively deliver the corresponding therapeutic parent drugs to target cells or to the target site. This invention will therefore primarily but not exclusively relate to tumor cells as target cells. More specifically the prodrugs are compounds of the formula V-(W)k-(X)1-A-Z, wherein: V is a specifier; (W)k-(X)1-A is an elongated self-elimination spacer system; W and X are each a 1,(4+2n) electronic cascade spacer, being the same or different; A is either a spacer group of formula (Y)m wherein: Y is a 1,(4+2n) electronic cascade spacer, or a group of formula U being a cyclisation elimination spacer; Z is a therapeutic drug; k, 1 and m are integers from 0 (included) to 5 (included); n is an integer of 0 (included) to 10 (included), with the provisos that: - when A is (Y)m: k+1+m ≥ 1, and if k+1+m = 1; - when A is U: k+1 ≥ 1.
本发明涉及一种前药,可以在首选作用部位激活,以有选择地将相应的治疗母药物传递到目标细胞或目标部位。因此,本发明主要但不仅限于将肿瘤细胞作为目标细胞。更具体地,前药是化合物V-(W)k-(X)1-A-Z,其中:V是说明符;(W)k-(X)1-A是一个延长的自我消除间隔系统;W和X分别是1,(4+2n)电子级联间隔器,相同或不同;A是公式(Y)m的间隔基团,其中:Y是1,(4+2n)电子级联间隔器,或者是公式U的基团,是环化消除间隔器;Z是治疗药物;k,1和m是从0(包括)到5(包括)的整数;n是0(包括)到10(包括)的整数,但前提是:当A为(Y)m时:k+1+m≥1,如果k+1+m=1;当A为U时:k+1≥1。
